Mitral valve -
| The cardiac valves keep the
blood moving in the right direction through the heart. The mitral valve
regulates the opening between two of the heart’s four chambers – the
left atrium and the left ventricle. As
the powerful left ventricle contracts (ejecting oxygen-rich blood
throughout the body), the mitral valve closes, thereby preventing a
backwash of blood ("regurgitation") into the left atrium. |
